Can someone explain what this means? What is the difference between this: keybd_event(RIGHT, 0, 0, 0); keybd_event(RIGHT, 0, 2, 0); and this: keybd_event(RIGHT, 0, 1 | 0, 0); keybd_event(RIGHT, 0, 1 | 2, 0); because when I execute this code I can't see no difference? Also, what is "byte bScan" for? In description it is: A hardware scan code for the key. What that means? 回答1: The simple (and

[Tip: when looking at Boost documentation for a new class, read the "examples" at the end first. You then have a sporting chance of figuring out what on earth the rest of it is talking about :-)] 回答2: map is

To select an certain item in the menu, one should use <C-N> and <C-p> to switch back and forth between different items. I feel that it is very inconvient .

Either it's true or false, I'm interested in any reference pointer on the subject. PS: I understand the above property will not be true for every objects that behave like a dictionary, I just

I am trying to bind an action to the media keys you find on newer Apple keyboards (Play, Pause , etc). It appears that you cannot bind to these keys using the regular hotkey API but it must be possible since iTunes clearly manages. Is there some tricky undocumented API that achieves this? Any help would be much appreciated. 回答1: After more extensive googling, this http://www.rogueamoeba.com/utm/2007/09/29/ seems to address the issue. There is

An example would be, when I pressed the a key it would print to the console The a key was pressed! It should also listen for the arrow keys/spacebar/shift key. 回答1: It's unfortunately not so easy to do that. If you're trying to make some sort of text user interface, you may want to look into curses . If you want to display things like you normally would in a terminal, but want input like that, then you'll have to work with termios , which

I tried using SCAN so that later on i can use MGET to get all the values, The problem is: SCAN 0 MATCH "foo:bar:*" COUNT 1000 does not return any value whereas SCAN 0 MATCH "foo:bar:*" COUNT 10000 returns the desired keys. How do i force SCAN to look through all the existing keys? Do I have to look into lua for this? 回答1: With the code bellow you will scan the 1000 first object from cursor 0 SCAN 0 MATCH "foo:bar:*" COUNT 1000 In result you will get a
